Lock_Guard Device Or Resource Busy. A calling thread must not own the mutex prior to calling lock or try_lock. Adopt_lock_t) constructor allows the boost:: In c++, when you have multiple threads accessing shared data, it's crucial to prevent race conditions where threads might interfere with each other's. And how to avoid it? You can't really reasonably check whether a mutex is locked, because one nanosecond after the check it can get unlocked. In addition, the lock_guard (lockable & m, boost:: The behavior observed is possible since you have ub in the code. When std::lock_guard is instantiated, it attempts to take the ownership of the mutex it is given (think of it as lock() is called on. According to 17.6.4.11, violation of a requires clause is ub. Often times a deadlock occurs due to a wrong order of acquiring locks: Lock_guard object to take ownership of a lock.
